Weird!..Got in my 3 today after it was sitting in the sun all day and the mirror thermometer said it was 79 degrees F..By the time I got home it was reading 92 degrees F, went in and checked the weather channel and it said we were currently at 103 degrees F...I think I need a new thermometer..

 

I noticed mine recently reading about 10 degrees colder than it actually is. I was just about to look up its location so I could check to see if it had mud on it or something. Let me know if you get yours back on track or if anyone else has had this problem
